JavaScript ternary operator and if/else statement

Question

Can anyone explain to me what is the difference between these two statements and why the second one does not work and the first one does:

They do the same thing. The second one doesn't work because you are not returning anything — bugs

You miss the return statement in the second example. It should be return (finalWord.length > 140) ? false : finalWord; — Weedoze

The second version is missing the return statement. It should be return (finalWord.length > 140) ? false : finalWord; or return finalWord.length > 140 && finalWord; — AndreasPizsa

It looks, you miss the return statement.

return finalWord.length > 140 ? false : finalWord;

You could shorten it to

return finalWord.length <= 140 && finalWord;

I am so stupid :)) I thought that the return statement was implicit when using ternary operator. thanks

@Dito if it was, then you wouldn't be able to write var myVar = someVariable == otherVariable ? "yes" : "no";
